FCT and Yeo Valley at Countryside COP2

Posted on November 10, 2022 by - News

On the 10th October Farm Carbon Toolkit’s Becky Willson and Liz Bowles co-led an event kindly hosted at Yeo Valley Organic Garden as part of the second Countryside COP (CCOP2).

Countryside COP is a hybrid conference held to align with COP to create space for the agricultural sector and rural economies to push ahead on climate change and sustainability. It was established to allow rural communities to come together and illustrate the opportunities that are available, along with contributions that are already underway to reach net zero. The event is also an opportunity to explore adaptation options, something of increasing importance as our weather patterns become more extreme, as seen so starkly seen this year. 

The first Countryside COP was set up in 2021 by the Agriculture & Land Use Alliance (formerly Greenhouse Gas Action Plan GHGAP). Organisations in the Alliance include:

  • ADAS
  • Agricultural Engineers Association (AEA)
  • Agriculture & Horticulture Development Board (AHDB)
  • Agricultural Industries Confederation (AIC)
  • Country Land & Business Association (CLA)
  • Linking Environment & Farming (LEAF)
  • NIAB
  • National Farmers Union (NFU)

In an NFU article leading up to Countryside COP1 the Alliance said

“This journey is complex, but there is no shortage of professionalism and knowledge within the rural community, and all who support food and farming. This is the time to utilise and invest in this expertise so we can help contribute to the government’s net-zero target, all while continuing to produce fantastic, affordable food for people at home and abroad”.

This year Farm Carbon Toolkit was one of a range of organisations including universities and farming bodies contributing to CCOP2. Through a plethora of 15 events running from the 10th-14th October all across the UK CCOP2 speakers were hosted from as far afield as Australia, Ghana and Zambia.

At Farm Carbon Toolkit we teamed up with our project partners at Yeo Valley who kindly hosted us, to talk about making the transition towards regenerative agriculture and about the findings so far in the project. The event was attended by a range of participants including farmers, education providers, NGOs and the general public. 

FCT’s event on ‘Soil Health and Water Security’ discussed the benefits that agroforestry can bring to grassland systems. It was demonstrated that the presence of trees can buffer extreme weather conditions such as the drought experienced this summer by supporting grass growth and therefore livestock performance, as it has done at Yeo Valley. Agroforestry can enable soils to retain more moisture, limiting the impacts of both droughts and flooding, so has a direct climate change mitigation potential.

Other findings demonstrated at the event included discussing how research carried out with Yeo Valley farmers has suggested that soil management practices, such as growing herbal leys, can increase soil carbon deposition below 10cm. The amount of carbon this is sequestering due to the range of practice uptake on trial sites is significant – it demonstrates a carbon stock improvement of between 20-40t/c/ha.

The event also showcased how significant discussions and events like this one can be in improving carbon literacy amongst attendees, crucial in moving forward together.

Our latest upgrade to the Farm Carbon Calculator

Posted on November 29, 2021 by - News

Today the Farm Carbon Calculator has gone live with a major upgrade. As part of our development cycle, every few months we deliver updates to ensure our calculator keeps up with the latest science, while also improving its features and usability. As the number of users continues to rise, we  regularly  update the tool to ensure it’s the best it can be and matches our users’ expectations.

The recent COP26 exemplified how carbon has shot up the agenda for everyone in societies across the world, and this fact is reflected in the number of farmers and growers we are engaging with at the Farm Carbon Toolkit. We have been advocating for over ten years that farmers and growers have a key role in cutting emissions and indeed in sequestering carbon in their biomass and soils, and we provide solutions for users to measure and manage carbon in their businesses. 

Farms are one of just two industrial sectors that can not just reduce emissions but also sequester carbon (the other being forestry). This means farming can play a positive role in the climate crisis by potentially drawing down atmospheric CO2 into its soils and biomass. Facing the climate crisis, we are here to support farmers and growers to make a positive contribution, as we all must do.

What’s changed

In this upgrade we have updated a wide range of emissions factors based on the latest research; including in Fuels, Livestock, Fertilisers, Crops, and Materials. This means up-to-date figures, more categories and therefore increased accuracy.

Major changes include a larger range of fertilisers, a huge range of branded sprays to choose from, a new way of recording livestock numbers – giving much more useful outputs, more animal feeds, new animal bedding section, a much greater range of bought in manures, and upgraded factors in fuels, electricity and travel.

There are new user features including an improved way of recording yields of crops, more FAQs to help you through the process, and videos to support you in filling in the Calculator.

On the Report Summary page, the emissions are now broken down into Scopes 1, 2 and 3, which makes Company Reporting easier and clearer. We’ve also separated results for carbon dioxide, methane and nitrous oxide, so users can understand which greenhouse gases make up their total carbon footprint. 

A brand new feature, and a great compliment to Carbon, is a way to measure Nitrogen. Thanks to funding from the WWF, and in conjunction with the Soil Association, our new ‘Nitrogen Module’ allows users to visualise the nitrogen flows in and out of their farm system. Nitrogen (N) inputs are built up from biological fixation, synthetic fertilisers and organic manures as well as purchased livestock and animal feeds. The N output is calculated from in-field N2O emissions as well as crops, milk and livestock sold and the N balance calculation provides an overview of the net change of Nitrogen over the year. 

The new Nitrogen Module shows overviews and details of the flows of N in and out of the farm

The process

It takes several months of work to prepare for an upgrade. We plan, prioritise, research, extract figures, build new functionality, review, then test, test and test again! 

The Calculator team is already planning the next update, which is scheduled for late February 2022. We will be working to update a raft of more emissions factors, reviewing the latest science (which is changing quite rapidly), and working on even more user features. Which all means that in another three months the Calculator will take an even bigger leap forward!

The Calculator can be used on all types of farms, including livestock, arable and horticulture

Working with consultants, larger companies and organisations

The Calculator will always be free for farmers and growers to use. But increasingly we have a new group of users who want to use the Calculator within their supply chains and as part of a consultancy service. 

For consultants advising farmers, we offer a licensing service, where they can receive training and access to the Calculator to calculate the carbon footprint of their clients, and deliver advice upon the results. For businesses and organisations managing groups of farmers and growers – such as buying groups, co-ops and larger food businesses, we offer a white label version of the Calculator. This is branded and tailored to the user, along with support from us, and a group admin function to manage and compare group users’ data.

Finding out more

We hope you find the Farm Carbon Calculator useful for your business, and take steps to reduce your carbon footprint. You can use the Toolkit for further help, advice and case studies https://farmcarbontoolkit.org.uk/toolkit.

Launch of Guide on Monitoring Soil Carbon

Posted on November 11, 2021 by - News

We’re pleased to announce the launch of a new guide for monitoring soil carbon. This practical field, farm and lab guide aims to answer key questions for robust on-farm field monitoring of soil carbon and associated indicators of soil health.

This guide has been produced as part of the Soil Carbon project and written in collaboration with Duchy College, Plymouth University, Rothamsted Research and the Farm Carbon Toolkit. It is designed and printed with kind support from the Farm Net Zero project, funded by the National Lottery Climate Action Fund.

Who is it for?

This practical guide is relevant to farmers seeking to measure and understand their soil carbon stocks – as well as landowners, advisors and researchers.

Supply chains and organisations seeking to reward farmers for improving soil carbon stocks will also find this guide helpful. However it should be noted that it’s not written as a formal standard or detailed protocol. The guide will be accompanied with detailed supplementary materials stemming from the ERDF Agri-Tech Cornwall funded “Soil Carbon Project”(2018 to 2021).

Why is this important?

Robust estimates of soil carbon stocks can be complicated. Not least because soil carbon levels are constantly in-flux with in-field variation. Estimates are also heavily influenced by the way in which we collect, process and analyse soil samples. In the Soil Carbon project, we’ve been working with research partners to investigate how soil carbon estimates are influenced by variables such as when the samples are taken, how many samples are taken and at what pattern across the field.

What does the guide cover?

The guide consists of answers to the following core questions:

  1. When to conduct your soil carbon sampling?
  2. What fields to select on your farm?
  3. How to sample within those fields?
  4. At what depths should samples be taken?
  5. How often should you repeat your sampling?
  6. How to collect and prepare your samples?
  7. What are the options for the lab analyses?
  8. What are the main soil health indicators that should be monitored?
  9. What are the outputs and benefits?

The role of soil carbon in natural climate solutions – new paper released

Posted on April 6, 2020 by - Insights

A new paper has been released in Nature Sustainability this month which highlights the potential for soil carbon sequestration as a climate solution. You can access the full paper here. The abstract is below.

Mitigating climate change requires clean energy and the removal of atmospheric carbon. Building soil carbon is an appealing way to increase carbon sinks and reduce emissions owing to the associated benefits to agriculture. However, the practical implementation of soil carbon climate strategies lags behind the potential, partly because we lack clarity around the magnitude of opportunity and how to capitalize on it. Here we quantify the role of soil carbon in natural (land-based) climate solutions and review some of the project design mechanisms available to tap into the potential. We show that soil carbon represents 25% of the potential of natural climate solutions (total potential, 23.8 Gt of CO2-equivalent per year), of which 40% is protection of existing soil carbon and 60% is rebuilding depleted stocks.

Soil carbon comprises 9% of the mitigation potential of forests, 72% for wetlands and 47% for agriculture and grasslands.

Soil carbon is important to land-based efforts to prevent carbon emissions, remove atmospheric carbon dioxide and deliver ecosystem services in addition to climate mitigation.
